Abstract (data abstract)
CERN-LEP. Measurement of the cross sections and angular distributions for hadronic and lepton pair final states in E+ E- interactions at CM energies near 189 GeV. The data are compared with the predictions of the Standard Model. SPRIMEis defined as the square of the CM energy of the E+E- system after initial-stat e-radiation.
